Solving the problems of comfort and efficiency for electric vehicles

As a supplier of electric vehicle motor controllers, the industry has always faced a core challenge: How can the electric drive system achieve a smooth driving experience and high torque efficiency while maintaining cost-effectiveness? After all, in real driving scenarios, one will encounter many complex driving conditions, such as in narrow alleys, with loads, or when climbing slopes on construction sites. These situations require that the electric drive system solution must balance the driving experience with the range of the vehicle.

 

Improve torque efficiency through hardware modifications

The configuration of any electric vehicle powertrain cannot be separated from motor and controller for electric vehicle. The 320V electric drive system platform of WISEDRV adopts permanent magnet synchronous motors. We deliberately chose the natural air-cooling solution (requiring assembly facing the wind) - without a liquid cooling circuit, without a water pump, and without the risk of leakage. This will make the subsequent maintenance of the system simpler, more reliable, and reduce many problems in maintenance to an almost negligible extent. For long-term operation of sweeping vehicles, this is a disruptive advantage. When your vehicle needs additional traction, the controller can smoothly output torque without wasting additional energy current. Less energy loss means that the vehicle can travel further with each charge, have less battery pressure, and have a lower overall usage cost.

 

Achieving High Comfort in EV Driving

The instantaneous acceleration start-up can seriously damage the experience of the driver and passengers, especially in construction machinery. Our designed high comfort ev motor and controller features active damping and torque-limiting slope function for impact. The controller precisely reads the sensor signal and eliminates the ripple of gear tooth torque. When the driver steps on the accelerator, the torque rises according to a third-order curve - reducing the "impact" sensation. The active damping function can also suppress the oscillation of the transmission system caused by load (such as when a sweeper vehicle enters or exits a gravel pile). This can reduce the vibration amplitude by more than 60%, allowing the operator to maintain a good driving sensation during long shifts.

 

Integrated VCU UDS OTA

We have developed the integrated VCU UDS OTA motor and controller, which features functions such as driving mode logic, speed calculation, and fault protection (overvoltage, overtemperature, active damping). The UDS diagnostic function enables real-time fault diagnosis and parameter monitoring via CAN2.0, allowing technicians to pinpoint the source of the problem without additional operations. The OTA remote upgrade allows fleet managers to optimize the torque profiles and damping curves of multiple sweeping vehicles or micro vehicles overnight, without the need to visit the repair station. Additionally, the system also supports hardwired wake-up and sleep modes.
